Hi; LTO with lld for ELF targets has just been fixed in master, 
after v1.28.1. Without `-betterC` at least, not sure if 
`-betterC` was affected too in some way.

Bumping LLVM to v13 wasn't trivial this time. There's 
https://github.com/ldc-developers/ldc/pull/3842 using an LLVM 
v13.0.1-rc2+, which fixed serious issues we've had with the gold 
linker (lld v13 was fine). You can download that CI artifact 
(with enabled assertions) and give it a try to see if it works 
for you:
